Abstract

PURPOSE:To attain reverse transfer from an absence transfer destination when an incoming call replied in deputy call for urgency by the absence transfer destination by inhibiting an absence transfer service only to the incoming call from a subscriber terminal equipment set as the absence transfer destination. CONSTITUTION:Suppose that the subscriber number of the subscriber terminal equipment 42 being absence transfer destination is registered in an area corresponding to the subscriber terminal equipment 41 of an absence transfer identification memory 5. In this case, when a subscriber terminal 4n calls the terminal equipment 41, a central control unit 2 compares the absence transfer destination subscriber number 42 with the subscriber number of the called subscriber terminal 4n. In this case, since they are not coincident, the absence transfer service is applied and an incoming call is given to the terminal equipment 42. In this case, if the content of a call requires urgency from the terminal 4n, the user of the subscriber terminal equipment 42 transfers reversely the call from the terminal equipment 4n to the terminal equipment 41. In this case, since the calling subscriber number 42 and the said absence transfer destination subscriber number 42 are coincident, the controller 2 does not perform the absence transfer service to the subscriber terminal equipment 41 but applies the usual call processing to transfer the call from the terminal equipment 4n to the terminal equipment 41.
